APPARATUSFOR'WEAMG oOlLl-:D-WIRE FABRIC.

.To all whont it may `cf'Jl/i/ciernl-' l Beit known that we, CLARENOEQLWHIEE and MARSHALL B. LLOYD, of llllin'neapolis,Y

Hennepin county, State of Minnesota, havev invented certain newV and vuseful Improvements in Apparatus for Weaving Coiled-Wire Fabric, of which the following isfa Specification. I

This invention relates to improvements in,

lo apparatus or 'machinerydesigned for weaving coiled-wire fabric I.for lr bed bottoms or other purposes; and the Objects we have in View are to provide' a machine that,willau'tlomatically weave a fabric of this kind, preferably of two independentwireswhich are similarly coiled and simultaneously,interlocked with the preceding wires,forminga fabric of 3o bed-frame and also preventing the wires from ing handled.

Other objects will appear from the following detailed description.

This' machine in its general mode of Operation issimilar to that shown and described in Letters Patent issued tous on October 20, 1891, No. 461,695.

In the laccompanying drawings, forming 4o part of this specication, Figure 1 is avplan view of a machine embodying our invention. Fig. 2 is aside elevation of the same. Fig.

3 is an elevation and partial section showing A the feed-rolls and the means for automatically stopping the machine' when the wires do not pass properly from thefeed-rolls into the fabric. Fig. 4-is a perspective gviewofj the mechanism employed for` connecting or disconnecting the driving mechanism from the movinglong'itudinally while the fabric is beceiver.

mechanism that controls the movement of the fabric. Fig. 5 is a side elevation showing the means employed for separating the rolls, cutting the wire, and moving the ends of the wires when other wires are to be run into the fabric at the same point as preceding wires for the purpose of forming arib therein. Figs. Gand 7 are respectively, an elevation and a section showing the means employed for separating fthe feed-rollsv after the running of each wire or set of wires. Fig. 8 is a transverse vertical ,section showing the receiver into ,whichl the wiresgare run and, showing also the means `for operating the pins andholding-bar that are used in connection with 1 said receiver.- Fig. 9 is also a transverse section through the receiver, Showing the roll over which the fabric; passes and the wires that are connected to the upright pins about which the fabric is formed. Fig.10 is a side elevation of a portion of the machine, showing the fabric passing therefrom and showing the means for evening upthe ends of the fabric and for crushing and cutting the ends of thel fabric. 5 Figs.` 11 and 12 are details showing the spring-wires thatl are employed for holding up thefabric while it is being evened up latthe ends,

` additional wires are to be inserted. Fig. 15

is a partial side elevation ofthe mechanism lshown in Fig. 14. Figs. 16 and 17 are details showing the meansv for longitudinally adj usting the receiver into which the coiled wires are run. Fig. 18 is a detail of the means for cutting the wire and showing also the position and arrangement of the device for automatically stopping the machine should the Wire double up between the coiler and there- Fig. 19 is also a detail of the wirecutting mechanism. Fig. 2O is a detail showing the knife for cutting the wire and also showin g the construction of the device we employ for moving the end of the coil in the receiver when a second set of wires is to be run in by the side of the iirst set for the purpose of forming a rib in the fabric. Fig. 21 is an end elevation, and Fig. 22 a side elevation, of the wire-moving device shown in Fig. 20. Fig. 23 is a perspective view of the roll that is located 'in the end of the receiver. Figs. 24 and 25 are details of the means for evening the fabric and crushing and trimming the edges thereof. Figs. 2G, 27, 2 29, and 37 are details of a modified form of automatic stop arranged between the reels and the coiler. Figs. 30, 31, 32, 3l, 35, and 3G are details of the coiler.

In the drawings, 2 represents the frame of the machine, which may be of any suitable size and construction. Arranged at one end thereof are the standards 3, in which are mounted in suitable bearings 5 the shafts 7 of the feed-rolls S. One of the shafts 7 is previded with suitable fast and loose pulleys 9 and 10, to which, by means of a suitable belt, power may be applied to the machine. The lower shaft 7 is provided with a pinion 11, (see Fig. 3,) meshing with a similar pinion 12 upon the upper shaft 7, so that the two shafts are driven simultaneously and at the same rate of speed. )Ve prefer to use feed-rolls S, Fig. 3,formed of independent sections,mount ed upon rubber or elastic or yielding cores or centers, whereby the rolls will accommodate themselves to inequalities in the diameter of the wire. These rolls are preferably secured upon the shaft 7 by suitable means, such as the collars 13 and nuts 14. )Ve do not in this application claim the feed-rolls having the yielding cores or centers, as we have claimed the same in a separate application for patent filed April 1l-, 1807, Serial No. 632,127.

The bearings 5 for the upper shaft are capable of a slight upward movement, being held in position by a spiral spring 15, (see Fig. 6,) arranged between each bearing and the cap 1G of the standard A short shaft 17 (see Fig. 7) is arranged in a bearing 1S at one side of the front standard 3, and the end of the shaft 17 projects beneath the box or bearing 5 for the forward end of the upper shaft 7. rllhe shaft 17is provided with acam projection, (shown by dotted lilies in Fig. 6,) so that by rocking the shaft 17 the upper feed-roll is slightly raised, thereby relieving the pressure from the wire and stopping its movement. Secured to the shaft 17 (see Fig. 5) is an arm 10, having a roll 20 secured to the end thereof, and this roll rests upon the curved surface of a block 21, that is adjustably secured upon a longitudinally-reciprocating rod 22. The rod 22 passes through a standard 23 and also passes over therecesscd top of a standard 2-1- and is connected at its forward end to an upright pivoted arm 25. Said arm is provided at its upper end with a roll 245, mounted upon a suitable stud, and said roll engages a grooved cam 27, that is mounted loosely upon the cross-shaft 2t The cam 27 has secured to it a plate 27', and said plate is engaged by projections 111 on the chain 103 hereinafter described. A pivoted arm 2G carries a roll 28, that engages recesses in the outer surface of the cam 27. Said lever has connected to it a spring 29, and by this means the cam is stopped in the proper position after each movement thereof. By this means the rod 22 is given a reciprocating movement, and thereby the wire-feeding rolls are intermittently separated while running at full speed for the purpose of stopping the wire after each coil is added to the fabric.

A suitable belt-shifter (see Figs. 1 and fl) is arranged in connection with the drivingbelt of the machine, this belt-shifter consisting, preferably, of a bar mounted upon the swinging arms 24, that are secured upon the standard a loop 25, through which the belt passes and by which it is moved from the fast to the loose pulley when it is desired to stop the machine. A lever 26 is pivoted upon the frame of the machine and engages the bar23. (See Fig. 3.) To the lower' end of the lever 2G is connected the spiral spring 27"', having its opposite end connected to the frame ot' the machine. A lever 2S" is pivoted to the frame of the machine, and a link 29 is connected to this lever and to the lower end of the lever 2G". A latch 30 is arranged beneath the frame of the machine in the position to engage the end of the lever 28 when said lever is raised into a horizontal position. lVhen the -lever 28" is raised into this position, as shown in Fig. fl, the belt is in engagement with the ixed pulley and the machine is driven. A lever 31 is pivoted upon a suitable support upon the frame of the machine, and itslower end engages said latch 30. (See Fig. The upper end of the lever projects a short distance above the frame of the machine, as shown in Fig. 3. A plate 32, secured to a rod 33, is arranged in front of the coiler and between said coiler and the end of the receiver. 'lhe lower end of the rod 3i) is secured by a suitable pivot in frontofthe upper end ofthelever Ill. lVhen the machine is running, this rod Si) and the plate carried thereby stand in an upright position, as shown in Fig. lf the wire doubles between the coiler and the receiver,

it will engage the plate 32 and move it back, so that it will drop over in the position shown in dotted lines in Fig. 3, striking the upper end of the lever 31 and moving said lever into the position shown by dotted lines in said figu re. This will release the lever 2S from the catch 30 and permit the spring 27, through the lever 2U, to move the driving-belt onto the loose pulley,and thereby stop the machine. From the feed-rolls S the wires pass through the coiler, which is located directly in front of said feed-rolls. wWe prefer to employ a coiler that is double and coil two wires simultaneously but independently, as hereinafter described. After the wires leave the coiler they enter the receiver 3l. (See Fig.

The belt-shif ter is provided with IOO IIO

605,831 f i s 18.) This receiver is provided with a rectan gular recess in'its upper surface, as shown in Figs. 8 and 9, and one wall of the recess preferably extends higher than the other. A 'series of vertical pins 35 are arranged inthe receiver 34and said receiver, except a short stationary section 34 at the forward end, (see Fig. 18,) rests upon the uprights 36, that are secured to stationary arms 37, through which the shaft 43 reciprocates and which forms guides forsaid shaft. (See Figs. 18 and 19.) The shaft 43 is reciprocated longitudinally by means hereinafter described, and said shaft is connected to said receiver, and thereby the receiver is given a reciprocating movement. A bar 39,' having a beveled edge 40, (see Figs. 8 and 9,) rests upon the top of one wall of the receiver and is connected by rods 41 and arms 42to the rock-shaft 43. To the rock-shaft 43 is also connected an'arm 44, and to the end of this arm is pivoted the rod 45, having the slot 46, through whichpasses a shaft 47, car ryin'g a cam 48, and the rod 45 is provided uponits upper end with a roll 49, which vrests upon the edge of said cam.v (See Fig. 8.) The cam 48 is provided with the two projections 50, which insure the stopping of the roll `49 at the right place. The rod 45 is also provided at its'lower end with the lug 51, which moves upand down in a hole in the bedplate of the machine, thus insuring the movement of the rod 45 in a vertical line. A spring 52 is'connected to the arm 44 and serves to draw down said arm andhold the roll-49 on the rod`45 in Contact with the surface of the cam 48, and thereby to cause the bar 39 to be moved back when the cut-away portionsof the cam come opposite the' roll 49. When the /bar 39 is moved forward, the beveled edge partially projects over the open top of the receiver and projects into the space between the lastcoil of the fabric and the next to the last coil, (see Fig. 9,) and, pressing upon the top ofthe last coil, which will be within the receiver, holds it firmly in positionwhile the next succeeding wire or wires are running into position. Arranged upon opposite sides of the receiver are the bars 52, each .provided with guidepins 53, which extend through the lower part of the receiver 34; '(See Figs. 8 and 9.) One of these bars is provided with a series of pins.

55, which project horizontally through the longer or higher wall of the receiver 34 and engage the coils of the fabric.

The other baris provided ywith a similar set of pins 55, which extend through the bar 39, also in position to engage the fabric. The pins 55 also serve as guides for the bar 39. Rock-shafts 56 and 57 are arranged below the bars 52 and are provided with arms 58, having forks at their upper ends to engage said bars 52 (See Figs. 8 and 9) andpermit 'said bars to move longitudinally with the receiver. The shaft 56 is provided with au upright arm 59, and the shaft 57 with a similar arm 60. (See Fig. 13.) Alink 61is pivoted to the end of the arm 59 and is provided'at its oppositel end with a Tyshaped slot 62,.that is engaged by a pin63 upon the arm 60.` The narrow part ofthe slot is uppermost, as vshown in Fig. 13, and the link is held by gravity, so that this part of the slot is in engagement with the pin63. This causes the two shafts 56 and 57 to rock in unison and lcauses one set of the pins 55 to be advanced into the fabric as the other set is withdrawn, and the distance between the ends of the pins is sufficient to permit the fabric to move a distance equal to the diameter of acoil at each movement of the pins. Vhen it is desired to separate the bars 52 for any purpose, the linkI 61 is raised, so as to bring the pin 63 opposite the long part of the slot 62, when the shaft 57 may be rocked independently of the shaft 56. A setscrew 64 is preferably provided in the link 61, projecting into the end of the slot 62 for the purpose of limiting this independent move'- ment of the shaft 57 and the bar Operated thereby.

For the purpose of rocking the shafts 56 and 57 we provide upon the shaft 56 an arm 65, which is provided at its end with an up right 66, carrying rolls 67 and 468, which engage a cam 69, located upon the shaft 47. By this means the'two bars 52 are alternately moved back and forth toward the receiver 34,'

erably provided with ribs or projections 72 upon its surface, which are employed for posi-` tively feeding the fabric by the roll. One of the standards is preferably located at some distance from the end of the roll, the roll being divided for this purpose, as shown in Fig.

l, so as not to have any'projecting end or bearing for the roll at its end, which might interfere with the free movement of the fabric. At its opposite end this roll is provided with a ratchet-Wheel 73,and an arm 74,pivoted upon the shaft of the roll, carriesa pawl 7 5, that engages with'the teeth of this ratchetwheel. (SeeFig-13.) The oppositeendof the arm 74 is pivoted to a rod 76, which extends across the machine and is provided with the slotted end, through which passes the shaft 47. The endof the .rod 76 is provided with a roll 77, that is engaged by a cam 78 upon the shaft 47. An arm 7 9,`connected to the arm 74, has connected to it a spring 80, the opposite end of the spring'being connected to the frame of the machine. Arubber block or cushion 7 9' is arranged below the arm 79 in a recess or pocket 79. The arm 79 forms means for operating the feed-roll by hand. By throwing up said arm or the pawl the ,roll may be turned backward by hand should IOO IIO
